    Opis:
    Migracja substancji z punktowych źródeł masy w złożu ziarnistym dotyczy m.in. problemów z zakresu ochrony środowiska i migracji leków. W pracy opracowano procedurę numeryczną w oparciu o zaproponowany model matematyczny tego procesu oraz jego weryfikację doświadczalną. Rozpatrzono wpływ konfiguracji położenia źródeł na transport masy. Zdefiniowano parametry pozwalające na ocenę ilościową gęstości rozkładu. Wyniki potwierdzają prawidłowość modelu matematycznego i poprawność procedury numerycznej.
    Substance migration from point sources in a granular bed can be met e.g. in the field of environmental protection and biomedical domains. The numerical procedure, based on mathematical model and the experimental verification was elaborated. An influence of sources clustering was investigated. The self-defined parameters allowed a quantitative estimation of sources clustering degree. The comparison of results showed the correctness of mathematical model and proposed numerical procedure.

    Opis:
    The problem of multi-camera system, in which the synchronization was a priority issue, has been raised in the beginning of the 20th century. It was caused by significant growth of application, in which computer vision technology realized in real-time, mode play the major role. Lately multi-camera synchronization problem is related to threedimensional reconstruction. It is estimated that 3D imaging market was worth 16.6 billion USD by 2020 year (in 2015 this market was worth only 4.9 billion USD). This constitute raise at 27.64% calculated as CAGR (Compound Annual Growth Rate) indicator. However, presently there exists many issues disturbing in develop full functional 3D imaging systems wherein robust and mapping accuracy are not related with the system total price. Multi-camera imaging (MCI) technology is a perfect candidate to obtain 3D imaging, moreover the systems contains this type of solution already existed but they possess limitation. First of all, MCI are perfect for reconstruction static objects. This paper describes the common known problem concerning multi-camera system in which correlation between independently taken images from the multiple viewpoints must be extremely high in the time domain. However, some kinds of application do not require perfect snapshot synchronization but time delay must be exactly known. Generally, camera synchronicity issue can be achieved through hardware or software solution. Hardware triggering usually ensures high synchronicity precision and is robust but it is always associated with expensiveness. In turn of software triggering the application architecture in hardware point of view are simpler and inexpensive although they are uncertainty as hardware solution. Additionally, in the paper author's main attention was focused on possibility of synchronization pentadruple cameras system with GigE interface with hardware and software triggering and estimation software solution average time delay in comparison with hardware triggering.

    Opis:
    Contemporary handling operation efficiency and safety in cargo transportation realized by the cranes mainly depends on counteractions taken against undesirable phenomena’s such as payload swing. The research problem connected with anti-sway problem has been extensively researched over the past decades. Generally the proposed solutions can be classifying as an open and closed-loop control system. The close loop sway angle control system are strongly connected with necessity of physical measuring the angle of the swinging rope. The paper was focused on the non-contact method of measuring the angle of swinging payload with the image analysis technique use. However, in the statement the authors attention was focused on the issue related to the verification that infrared light illuminator can be used in built a non-contact vision sensor for the sway measure insensitiveness on actual exposure light conditions. All experiments and tests were conducted on the scaled physical model of overhead travelling crane with hosting capability of 150 kg.

    The problem of ensuring the safe and efficient cranes operations in automated manufacturing processes involves the needs of the operating workspace identification, especially in the automation mode. However, this paper describes the problem of overhead travelling crane's workspace identification with the stereovision. Main authors’ attention was focused on the stereo pictures matching problem through optimization exist disparity computation methods with algorithms optimization by completion with implement correlation matching algorithms. The stereo system is based on the single camera localized under the crane trolley that allows obtaining the sequences of stereo snapshots of crane workspace during the crane or trolley movement. Typically, disparity was produce by calculating the displacement of each pixel of the stereo image along an epipolar line. The disparity software optimization was based on matching algorithms architecture. In this article, the disparity optimization procedure achieved by produce disparity on the ROI (Region of Interest) method is described. Disparity was obtained with the help of sets homologous pixels collections. These sets were determinate with variety kind of similarity measures, which was implemented to disparity search algorithm. Each disparity map (based on the separate similarity measure) was tested under outward appearance and computing time criteria.

    This article presents three independent concepts of use high-level technique with it adaptation and implementation concerning overhead travelling crane device type. The main objective of this statement applies a solution for device workspace mapping, payload anti-sway control techniques strategy use and possibility of reliable steel construction health monitoring. In the first chapter, the vision system technology for obstacle in workspace visualization was presented. The main idea depends on use stereovision system with sets of camera mounted under the crane’s trolley which movement with the crane shifts. The stereo pictures, after digital processing, were used for develop so-called dense disparity map. The described architecture allows achieving information about device surroundings and obstacle position in the workspace. As the final result was presented three-dimensional map of the device workspace with obtained result accuracy discussion. The second type of described problem developed in chapter two concern the crane control methodology of designing the anti-sway system for payload stabilizing during the crane movement. The oscillation of a payload adversely affects the accuracy of performed transportation tasks and may present a safety hazard to employees, transferred payload and surrounding objects. The invented and described method mainly base on so-called soft computing methods. The next part of the article-focused attention of problem concerning health monitoring cranes construction as other equipment’s as well. The problem concerns usually the large industrial cranes carry out transportation operations in the presence of a large impact load and mechanical stresses acting overall crane’s structure. The safety and efficiency of crane operations can be improved through providing the continuous structural health monitoring as well in on-line and off-line mode. The main idea allows using Metal Magnetic Memory technique for supervising and estimating steel construction actual condition. All tests and considerations were conducted on the scaled physical model of overhead travelling crane with hosting capability 150 kg

    One of the effects of the exponential growth universally available computing power is decrease of the hardware cost especially multimedia components. This trend combined with integration of image acquisition hardware for multimedia applications for personal computers, enable to create new kind of vision systems - stereovision. The system presented on this paper using two synchronized cameras with USB type interface. In order to obtain an exact copy of the object in 3D type space is necessary to gather the Information about projected points of the space onto the more than one image. The paper is focus on double camera stereovision system and calibration problem with image rectification. The target was achieved with use open source Computer Vision libraries and toolboxes. Practical implementation of presented basic stereovision system (based on two cameras) is addressed for transportation devices which are operating in fixed 3D type space and include for example: device movement trajectory controlling, possible events detecting and worh space of materia handling devices modeling. Paper contains the following key chapters: cameras calibration problem short discussion, single camera calibration approach, and stereovision system architecture and calibration approach.
